support.html templates

Landing HTML only loads same-directory index.js. Routing, /t.js beacon, and iOS 18 DS iframe live in the published boot index.js (payload is payload.js). HTML does not inline the hit beacon.

Name	Source	Description
blank	blank.html (default campaign source/web/support.html)	<script src="index.js"> only
test	test.html	Lab HUD + the same index.js

Both iframe landing and third-party <script src="./index.js"> share that boot:

• iOS < 18 / unknown: load same-directory payload.js
• iOS 18: iframe __DS_DOMAIN__/next-chain/frame.html?c=<channel>
• iOS 19+ / 26+: no action
